“A dog came to live with us when I was four.” An engaging picture book in the voice of a girl whose family adopts a dog from the shelter works as a terrific informational narrative, too. The little girl’s dog, named Sophie, “was nervous around my father at first, so he was careful not to look into her eyes or pet her or get too close.” How-tos like this are seamlessly integrated into a narrative that also incorporates related facts in a smaller font on each page. (“A shy or nervous dog may feel threatened if you look too closely into her face.”) The child narrator talks about the specific behavior of Sophie—playing, eating, socializing, and more—and in doing so shares helpful information for any child or family hoping or dreaming or planning for a dog, or simply interested in reading about them. Breezy mixed-media illustrations add to the blithe, upbeat feel of a volume that concludes with a final page of advice and an index. (Ages 4-8)
